IMPROVEMENT IN BEDSTEAD-FASTENINGS.

Specification forming part of Letters Patent No. 222,129, dated December2, 1879 application filed August 11, 1879.

To all whom it may concern:

Be it known that I, PETER FORG, otvSomerville, county of Middlesex,State of Massachusetts, have invented an Improvement inBedstead'Fastenings, of which the following description, in connectionwith the accompa- This invention relates to an improved adjustablefastening-bolt for uniting the side rails and head and foot parts ofbeds, and other articles where like joints are common.

In this my invention a headed screw-bolt, provided with a fixed collar,has its nut fitted into the side rail, and the head of the boltprojecting beyond the end of the side rail is adapted to enter a mortisein the post, and engage a head-plate having a contracted eye, and whenso engaged the bolt may be turned to draw the side rail and posttogether and make a very firm, rigid, and close joint.

Figure '1 represents part of a side rail and post, showing my improvedadjustable screw as engaging the head-plate, secured in the post, thewood being broken away about the bolt and plate to show theirapplication and i Fig. 2 a face View of the head-plate detached.

Most heavy bedsteads, and those of the better class, where a very firmand close joint is desired, have their side rails and posts connected bymeans of bed-serews. The nuts of these screws are fixed in the siderails, and the screws are passed through the posts, and the heads of thescrews are made square, to be engaged by a wrench; or their heads areprovided with holes to be engaged by a rod or pin.

Considerable time is wasted, and it is quite a difficult piece of workto put together a bed with the common bed-screw.

My improved screw-bolt a has a threaded portion, b, (shown in dottedlines,) to engage fastened in the side rail, cl. The screw-bolt has ahead, 6, which may be made to extend more or less beyond the end of theside rail, d, according to the distance between the face of the post fand the rear side of the metallic head-plate g, which is let into a slotin the post f. The side rail has the usual wooden dowel or pin h toenter a hole, z, in the post.

A side rail having a screw-bolt, (I, placed in it, as shown anddescribed, may be connected with the post, it having the head-plate gplaced therein, a passage, 4, having been made in the post coincidingwith the eye or passage 2 of the plate 9, by inserting the head 6through the opening 4 of the post and the larger portion 2 of the eye ofthe plate g, and moving the bolt so that its shank, near its head,enters the smaller part 3 of the eye.

To make the joint very close and tightI then insert a rod, m, as at Fig.1, into one of the eyes 5, made in the bolt between its head andscrew-threaded part, turn the bolt so that it moves farther through thenut in the direction of the arrow, Fig. 1, thereby causing the head ofthe bolt resting against the rear of the head-plate to draw the face ofthe post and end of the side rail closely together, making a most rigidjoint. Instead of the holes or eyes 4 and pin m, I may make the boltsquare, or of other angular form, at the part marked a, so as to bereadily engaged by a wrench, to thereby turn the screw.

I claim- A bedstead-fastening composed of the plate 9, set in a recessin the bed-post, the headed screw-bolt a, its fixed receiving-nut 0, theboltoperating collar n, fixed upon the said bolt, and accessible fromthe exterior, for tightening or drawing together the parts after theyare connected, substantially as shown and described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

PETER FOR'G.
